He often draws laughs in the locker room when reciting a popular line from a segment that appeared years ago on Chappelle’s Show. The sketch featured comedian Dave Chappelle playing the role of musician Prince in a basketball game.

One of the signature lines is how Bosh explains becoming a better long-range jumpshooter, which has made the Miami Heat offense even more dynamic. He made 3 of 4 from the 3-point line in Sunday’s victory against the Milwaukee Bucks in Game 1 of their first-round series. Game 2 is Tuesday at AmericanAirlines Arena.

Bosh is now a legitimate three-point threat because of a line used by a comedian in a skit. After making a no-look pass, Chappelle demands a teammate to “shoot the J, shoot it.”

Simple enough for Bosh.

“Shoot the J,” reserve center Chris Andersen said as Bosh was speaking to a reporter. “Shoot it from the visitors parking lot!”

Bosh jokingly fired back, “I shoot about a thousand a night.”

The transformation began two years ago when he slowly started working more on his outside game. It increased during last year’s playoffs when coach Erik Spoelstra asked Bosh to practice from the perimeter while he was injured during the second round.

“We were trying our best to predict the future,” Bosh said. “It was something we were talking about the last two years, being able to stretch the floor as a big. It’s more effective for the team. It just works out sometimes.”

The result was Bosh making a career-high 21 3-pointers this season, nearly matching his total from the three previous years (24). Even though he shot just 28 percent, opponents have to at least respect him behind the 3-point line. He hit a game-winner from the arc in the Heat’s late-season victory against the San Antonio Spurs, a game they played without LeBron James and Dwyane Wade.

“He’s embraced so much of what we’ve asked him to do to get comfortable, to have a growth mind set,” Spoelstra said. “ … We asked him to start shooting 100, 200 threes every single day in the corner. This year, he added that to his routine. At times, the last three weeks he’s been shooting more.”

Bosh hangs his blue Shooting Stars jersey from the All-Star Weekend competition in his locker as a reminder to keep shooting. He puts in work mostly after practice, but there are times he makes late-night visits to the arena with close friend Geno Grey.

The two take advantage of the automatic rebounding machine on the practice court, allowing them to “work smarter, not harder.”

“I shoot until it feels good,” Bosh said. “It’s a lot of shots, but you just shoot until you get confident. It doesn’t matter if it’s after practice, before, at night, in the morning. It’s any time I have time to get shots up.”

The benefit for the Heat is it makes them even tougher to defend. Bosh spreads the floor, creating room in the paint for James and Wade. It forced Bucks shot-blocking center Larry Sanders away from the basket, playing a factor in James shooting 9 of 11 from the field.

“A lot of credit goes to Chris for changing his game and really working on his outside shot,” Wade said. “He’s just comfortable. We’re as comfortable with him shooting (the three) as we are with Mike Miller or Ray Allen shooting it.”

It says something when Andersen, the Heat’s energy player, referred to Bosh’s shooting in Game 1 as “it energized everybody.” Still, the coaching staff isn’t trying to morph Bosh into a 3-point shooter. The objective is for him to affect the game in the high and low posts while occasionally drifting to the arc.

Even Bosh says he still loves playing on the block and wants to avoid the label of being a “shooter.” When asked if he’d ever entertain the idea of participating in the league’s 3-point contest, he said it’s best to leave that to the professionals on the team such as James Jones, Allen and Miller.

“Nah, I’d bomb in it,” Bosh said. “I’d get out there and just shoot terrible.”
